From Wikipedia, the free encyclopedia

The BOP divides facilities into various security levels ranging
from ADX Maximum Security (Super Max), High, Medium, Low, Minimum,
and Community Corrections Centers. Examples are the ADX facility in
Florence,
Colorado; High security such as Lewisburg and Atlanta, and
numerous other lower level facilities throughout the United States.
A list of all the various facilities within the BOP system is at http://bop.gov.

Although the more common BOP facilities mentioned in the media
are the High and Medium, the minimum-security facilities, commonly
referred to as Federal Prison Camps, are usually the most
understood.

Federal prison camps are now more commonly referred to as
Federal Prison Camps ("FPC") or Satellite Prison Camps ("SPC"). The
FPC are usually stand alone facilities that are self-contained and,
more often than not, found adjacent to a military or other
government installation. The SPC is usually co-located with a
higher security BOP facility (ADX-High) and is designed to provide
the workforce to assist in maintaining the infrastructure of the
entire facility - providing landscaping, repair services, and a
host of other daily duties.
